cient. means for accurately placing and se curing. drawer stops to railsor sills before the latter shall have been. built into the furniture. r

A further object isto provide meansfor 1 applying and. securing drawer.stops, in

which the stop may be previously assembled in. portable, receptacleswhich may be" insert ed'intothe magazine portion of the machine and fedtherefrom, one at a time, to. the driving means, each of saidreceptacles constituting, when in place inthe machine, a removable,lining for the magazine.

' A further object is to so construct and mount the; magazine thatit maybe removable to facilitatethe insert-ion of:a receptacle With theseandother objects in view, the invention consists in certaln novelfeatures of construction andv combinations of parts as hereinafter setforth and pointed out inthe claims.

In the accompanying drawings; Figure 1 is a side elevation; partly insection of a ma chine embodying improvements; Fig. 2 is a section on theline 22 ofFig. 1; Fig. 3 isja section on the line 3-3 of Fig. 1; Fig. 4is a section on the line 47% of Fig. 1 Fig.

5 is a plan view with themagazine removed Fig. 6 is a detail viewshowing the magazine, and Figs. 7 and 8 are views of certaindetails.

I represents a frameupon which a metal P a m s. igi ly sec red Twoparallel standards 3-3 project upwardly from the platform and aresuitably spaced apart to form guideways for a re clprooating head 4,said standards being madeon their inner sides: with elongated.

shoulders 5 on which the head 4: may slide. The upper face of the head ais recessed to receive the butt end portion of a driver plate 6, thelatter having a recessed free end to conform approximately to theexternal shape of the drawer stops to be driven into the rails or sills.Guide plates 7, 7, are secured upon the-standards 3 and overlie thehead. 4: and driver plate 6. i

A block 8 is located forwardly of the standards 3 so as to be disposedin front. of

the spacebetween' the standards, said blockbeing. provided at its basewith lateral pro jections secured to' the platform 2. The block 8 is sodisposed that when the driver plate is projected, the latter will moveover the upper face of saidv block. At its side edges, the block 8 ismade with ledges 9 which are undercut to form guide-ways for the sideedges of the driver plate. I

Uprights 10, 11 are secured to the sides of the block 8 and projectabove the same, the portions of said uprights being provided.respectively, with inwardly projecting flanges 12 and thus constitute aholder for a magazine 13. The rear flanges of the uprights terminate attheir lower ends slightly above the upper face of the block 8 and serveto assist in guiding the driver plate. The forward edges of the uprightsand their flanges are notched to receive the ends of a crossbar 14:,thelatter being spaced slightly from the upper face of the block 8 to forma discharge slot 14* for stops 15. The cross bar 14 may be provided witha notch 16 for a purpose hereinafter explained.

The magazine 13 may be conveniently made of sheet metal bent to form arectangular receptacle having an elongated opening 16 in its front. andthe upper end of the magazine'will preferably be provided with inwardlyproiecting flanges 17. The maga zine will be held removably in theholder formed by the uprights 10-11 by means of a spring-pressed latch18 mounted in the upright 10 and adapted to engage in a hole in thelower portion of one side wall of the magazine. The stops 15 arecontained in an elongated-receptacle 19 which may be made of pasteboardand may be packed at the source of supply of stops, the receptacles 19may be provided with removable covers to facilitate handling andtransportation, but when the stops are to be supplied to the machine,the cover of a receptacle will be removed and one end of said receptaclewill also be removed. The magazine will be removed from the holder andthe receptacle containing the stops will be inserted bodily into themagazine through the lower end of the latter. In order to prevent escapeof the stops while the magazine is being placed into its holder, a pinmay be passed through alining holes in the lower portion of themagazine, the front'end of said pin entering the notch 16 in the crossbar 141. After the magazine shall have been inserted into its holder,the pin may be withdrawn. hen the magazine is in place in the holder,its lower end will rest upon the ledges, and the lower end of thereceptacle 19 (which latter 'forms a temporary lining for the magazine)also rests upon said ledges 9. Thus it will be seen that when themagazine is supplied with a receptacle containing a number ofsuperimposed stops, shall have been applied to the machine as abovedescribed, the lowermost stop 15 will rest upon the upper face of theblock in line with the driver 6 so as to be projected through thedischarge opening 1 1 when said driver is moved forwardly.

An upright bracket 20 is located on the platform 2 and spaced from theblock 8 and if desired, this bracket may be made integral with theplatform. Pins 21 project inwardly from the lower portion of the bracket20 and upon these pins a shoe 22 is supported. This shoe may be facedwith a wooden strip 23 (preferably having a curved upper face) toreceive and support a rail or sill into which'the stops are to bedriven,said rail or sill being inserted between the block 8 and thebracket .20 so that the latter will form a driving abutment.

. The end portions of the shoe are made with beveled or cam faces whichengage the pins 21 so that when the shoe is moved endwise, it will beraised or lowered so that it may be adjusted to regulate the distancefrom the edge of the rail or sill at which it may be desired to locatethe stops. The bracket 20 is made with an inclined slot 24 through whicha screw 25 passes and engages in a threaded socket in the shoe. By thesemeans, the shoe may be secured at any desired adjustment. h

For the purpose of operating the driver, the devices now to be describedare employed.

One member of a toggle lever 26 is pivotally connected to the slidinghead 4 of the driver and the other member of said toggle lever ispivoted to fixed lugs 27 on the platto the toggle lever at the pivotaljuncture of its two members'and depends therefrom. A rod 29 is securedto the coupling 28 and extends downwardly through an opening 30 in theplatform 2, the lower end of said rod being connected with a treadle 31mounted in the lower portion of the framework 1. This treadle and theparts with which it is connected is maintained in and returned to normalpositions, by means of a spring 31*, one end of which is attached to thetreadle and the other end to the frame 1. i i 1 It is apparent that whena rail or, sill is placed in position'betweenthe block 8 and the bracket20 and the treadle is depressed engaged by the coupling28 when thedriver is withdrawm- -said screw alsobeingpositioned to be engaged byone member of the toggle when the latter is in its lower position andthe driver is projected. It is apparent that by adjusting the screw 32,

the throw of the driver may beaccurately adiusted.

Having fully described my invention what I claim as new and desire tosecureby Letters-Patent, is

1. In a machine of the character described, the combination with ahorizontally movable driver. means for supporting the same, and meansfor reciprocating said driver, of a fixed bracket in front of the driverand having an inclined slot, pins projecting from said bracket. a shoedis osed-between the driver support and said bracket for supporting arail to receive stops, said shoe having inclined faces to engage saidpins, and a screw engaging said shoe and movable in the inclined slot inthe bracket.
